So when I just played Fortnite (PC) I pressed something on the keyboard and now if I'm in Fortnite the screen "right" and the quality is quite pixilig and the buttons are not there where they are displayed. If I press the Windows key, everything is much fatter, but when I'm out of Fortnite everything is back to normal size.
What have I pressed how to make it normal again?
Addendum everything is pixelated
You could check the resolutions and the aspect ratio.
